Bottom Line: The difference between the groups was statistically significant (P <0.01).As for the cleaning results, the debris collection in the EndoVac and tip-vented groups was the least in the apical third.In the control and the side-vented groups, the debris was the greatest in the apical third, but this difference was not significant among the three experimental groups.

ABSTRACT

Background: Root canal irrigation carries a risk of extrusion of irrigant into the periapical tissues which can be associated with pain, swelling, and tissue damage. Studies have shown less extrusion with sonic or apical negative pressure devices compared with syringe and side-port needle or passive ultrasonic irrigation with continuous irrigant flow. This study aimed to evaluate the effectiveness of the EndoVac irrigation system, regarding 1) debris removal and 2) the control of apically extruded irrigating solution.

Methods: Fifty extracted human single-rooted teeth were used in this study. The teeth were then randomly divided into three experimental groups according to the type of irrigation used and one control group. In group 1, irrigation was performed using the EndoVac irrigation system. In group 2, irrigation was performed using a 30-gauge, tip-vented irrigation needle. In group 3, irrigation was performed using a 30-gauge, side-vented irrigation needle. The control group received instrumentation with no irrigation to serve as a control for cleaning efficiency. Root canal instrumentation was performed using the Profile NiTi rotary system with a crown-down technique. All of the experimental teeth were irrigated with the same amount of 5.25% sodium hypochlorite. The amount of extruded irrigating solution was then measured by subtracting the post-instrumentation weight from the pre-instrumentation weight using an electronic balance. The cleanliness of debris removal was evaluated using scanning electron microscopy.

Results: EndoVac irrigation had the least amount of extrusion followed by the side-vented and tip-vented method. The difference between the groups was statistically significant (P <0.01). As for the cleaning results, the debris collection in the EndoVac and tip-vented groups was the least in the apical third. In the control and the side-vented groups, the debris was the greatest in the apical third, but this difference was not significant among the three experimental groups.

Conclusions: The EndoVac irrigation system extruded significantly less irrigant solution than either needle irrigation system. Debris collection was the least in the apical third for the EndoVac irrigation system. No significant difference was found in the cleaning efficiency among the three irrigation systems.

Figure 2: The percentage of debris (mean ± SEM) in the apical, middle and coronal thirds of the root canal using the three systems (E-EndoVac, TV-Tip Vented, SV- Side Vented).

Mentions: All fifty teeth in the three experimental groups and the control group were included in the cleaning analysis. The amount of the remaining debris in the coronal, middle and apical thirds was assessed, and the percentage of debris was calculated. The results are shown in Table 1 and Figures 2 and3. The EndoVac system had minimal debris in the apical third followed by the coronal and middle thirds. The tip-vented needle irrigation system also had the least debris in the apical third (28.23%), followed by the middle third (34.01%), and then the coronal third (38.47%). For the side-vented needle irrigation, the mean debris score was the least for the coronal third (20.45%), followed by the middle third (23.35%), and then the apical third (32.79%).
